'Ringer' returns: Catch up before you watch and preview the new episode

"Ringer" is back this week and things are getting even more complicated.
Sarah Michelle Gellar is back as sisters Siobhan and Bridget. Need a little refresher? We've got a video to help you catch up on the show and get ready for the new episodes.

We've also got a preview of Tuesday (Jan. 31) episode, "It Just Got Normal." Bridget hosts a fundraiser that Greer (
Madchen Amick) is holding for Juliet's (
Zoey Deutch) school and realizes that Greer knows one of Siobhan's deep dark secrets.

While back in New York, Siobhan discovers that Bridget has settled into her former life more easily than Siobhan expected and she is determined to change that. Meanwhile, Malcolm (
Mike Colter) decides to work for Andrew (
Ioan Gruffudd) at Martin/Charles in order to keep an eye on him, and Henry (
Kristoffer Polaha) mourns the death of his wife.
